iwlwifi: introducing the drv object's flows
Fetch the fw and spawn the op_mode. The op_mode that we need to fetch is determined from the fw file. Since the fw is fetched very early in the init flow, we can determine what op_mode to spawn.

| * DOC: Driver system flows - drv component | ||
| * | ||
| * This component implements the system flows such as bus enumeration, bus | ||
| * removal. Bus dependent parts of system flows (such as iwl_pci_probe) are in | ||
| * bus specific files (transport files). This is the code that is common among | ||
| * different buses. | ||
| * | ||
| * This component is also in charge of managing the several implementations of | ||
| * the wifi flows: it will allow to have several fw API implementation. These | ||
| * different implementations will differ in the way they implement mac80211's | ||
| * handlers too. | ||
| * The init flow wrt to the drv component looks like this: | ||
| * 1) The bus specific component is called from module_init | ||
| * 2) The bus specific component registers the bus driver | ||
| * 3) The bus driver calls the probe function | ||
| * 4) The bus specific component configures the bus | ||
| * 5) The bus specific component calls to the drv bus agnostic part | ||
| * (iwl_drv_start) | ||
| * 6) iwl_drv_start fetches the fw ASYNC, iwl_ucode_callback | ||
| * 7) iwl_ucode_callback parses the fw file | ||
| * 8) iwl_ucode_callback starts the wifi implementation to matches the fw | ||
